Sports reviews of SIGMA BC1606L DTS Wireless Bicycle Speedometer

Customer Review: Great so far
Sport shop rating: 5 Stars

I've only ridden once with this, but it's as promised (though I bought it elsewhere), wireless speed & wireless cadence.

The only real negative I've had is mounting the speed transmitter on my front fork. It's an aero design and I had a tricky time getting it close enough to the spokes without it having a tendency to either fall into or away from the spokes, depending on orientation. I did use a bit of duct tape rolled backwards to increase the friction on the fork, though that wasn't really necessary, as the maiden ride showed that it is sufficiently on the fork. Otherwise, mounting options are good. It fits stem or handlebar orientations. The speed transmitter claims a max range of 30 cm, but it is actually further than that.

It has only two display lines, unfortunately. One is always speed. The other can be stop watch, cadence, average cadence, average speed, etc. The computer supports two bikes (if they have separate transmitters, you need simply to move the comp to the second bike and it picks up automatically).

Although its speed reading is in .5 increments, which I thought would be a problem, its trip distance and average speed both go to 1/100th of a mile, which is fantastic (overall odometer over multiple trips is at the single mile increment). There is a down or up arrow if you're currently substantially below/above average speed. If within about 1 mph, there is a black square by your speed.

It appears that the cadence does not turn on unless the speed is going, so I don't think that this would work on a trainer for cadence unless you had its speed setup to run off the back wheel (which it lacks the range for). When you stop moving, the thing pauses. When you start moving, it starts again--no need to press a button or anything.

The night feature is cool if one rides at night (most don't!).

If you want double wireless, this appears to be the cheapest computer with that, and it has a solid set of functions.

*EDIT* In fact, this works just fine with cadence-only. I just had it on my trainer and confirmed it; the front wheel does not need to spin for the computer to function.

Description of SIGMA BC1606L DTS Wireless Bicycle Speedometer

The BC 1606L DTS wireless is for dedicated cyclists. DTS stands for digital transmission system, providing zero cross talk with other computers and ensuring that the data on the computer is your own. The backlight gives optimal readability of this information even in the dark. An integrated storage chip prevents the loss of set values during battery change as features such trip section counter, timer, and second wheel size are programmable. Cadence is available as an optional accessory for this model. With the wireless receiver integrated into the bike computer, it can be mounted on your stem or bars. 16 Functions Wireless: speed, avg speed, max speed, speed comparison, trip distance, total distance bike 1, total distance bike 2, total distance bike 1 + 2, clock, ride time, low battery indicator, two bike programmable, total ride time bike 1, total ride time bike 2, total ride time bike 1+ 2, memory back up function. Wireless Cadence can be added with option DTS cadence transmitter, programmable trip segment, programmable timer.
Sigma's BC 1606L DTS is the top model for the most demanding of riders, even at night. The BC 1606L DTS wireless succeeds in this not only by providing a better overview of the essential information during a ride by hiding the total accumulated functions and cadence if not installed, but through its backlit readout that delivers optimal readability of information even in the dark. In addition, an integrated storage chip prevents the loss of set values during battery change as features such trip section counter, timer, and second wheel size are programmable. Cadence is available for both computers optionally. The set is equipped with a digital radio sensor. The receiver is integrated into the bike computer. A wireless cadence set is available as an option.

Digital Transmission System (DTS) Explained
With 2-channel radio transmission (km/h and pedal frequency) and 100% digital encoding without data loss, the DTS system guarantees 100% data security of current speed and pedal frequency values during wireless reception. It does this by calculating all relevant data, encoding it and transmitting it in data packets to the integrated receiver in the bike computer. Disturbances such as power lines or mobile phones are no longer a problem as transmission is carried out over the so-called low frequency. A double security system also ensures that only the data packets from your own transmitter are evaluated by the receiver. This means that group rides are no problem.

A further security measure is redundant data transmission so that no data can be lost. The size and quality of the receiver has also been optimized by a specially developed Sigma chip (ASIC) and integrated into the bike computer which also saves on battery life.
